Answer:
A
Step-by-step explanation:
500 cubic yards :) I think.
Answer: 9:5
Step-by-step explanation:
81:45 I first just divided them both by three and got 27:15 then they were both divisible by 3 so then I got 9:5
96+ 3.7 = 99.7
I'm sure its right
Answer:
cot x and sec x
Step-by-step explanation:
Given are 4 trignometric functions defined in the interval [0,\pi]
We are asked to identity the functions which can take values more than 1.
We have
![f(x)=sinx : f(x)= cos x](https://tex.z-dn.net/?f=f%28x%29%3Dsinx%20%3A%20f%28x%29%3D%20cos%20x)
have values always between -1 and 1 for any value of x
Hence sinx and cosx cannot take values greater than 1.
![f(x) =cotx](https://tex.z-dn.net/?f=f%28x%29%20%3Dcotx)
This value being ratio of cos to sin will become greater than 1 whenever cos >sin value.
SO this function can take values >1
![f(x)=secx](https://tex.z-dn.net/?f=f%28x%29%3Dsecx)
This function being reciprocal of cos function always can take values outside
(-1,1)
Hence this value can be greater than 1
